of course i tried to set it manually with --newmode, --addmode default and so on. xrandr adds the new mode to the default screen but cant activate it!

however, when i boot a knoppix live system via usb, xrandr shows a max resolution of 1024 x 600, which seems quite strange to me and knoppix correctly sets the right screen resolution for me!

so, as we can see, there are definitely drivers for my graphics card under linux in general, but as the gentoo live dvd doesnt seem to have them included.......maybe they havent been ported to gentoo?? that would be my worst fear!

X works without a xorg.conf, yet i tried so many things like modelines in the screen section, virtual resolutions...nothing works!

then i created a complete monitor section and it shows the right settings, so my edid data seems to be read corractly:

I suspect you have a framebuffer driver enabled in the kernel and not inteldrmfb + KMS ... or both are enabled and the former takes precedence. You might also have an empty VIDEO_CARDS= and so all xf86-video-* are installed (including xf86-video-vesa) ... its difficult to say from the above.

.... and nothing should be enabled under "support for frame buffer devices" ... build and install the kernel.

You would then set VIDEO_CARDS="intel" in /etc/portage/make.conf and "emerge -a @x11-module-rebuild". If you have this set then you should be fine with the just the kernel changes, if not then you may need to run 'emerge -a --deplcean' to remove any xf86-video-* drivers that were installed.

When booting inteldrmfb should auto set the video resoultion via KMS (Kernel Mode Setting) if the EDID is detected correctly ... which most likely it is.

Please make sure to remove any files under /etc/X11/xorg.conf.d ... if your using 'udev' then the xorg should work fine without any additional configuration.

to find out if thse things are enabled in the kernel there is a command i think which shows either "y" or "n" but i cant remember it....problem is that i dont really now exactly which option it is to look at

EDIT: or do i just type these as commands so that the options are set correctly?

The following will provide a list of whats currently enabled:

Code:

# awk '/AGP|(DRM|_I915)/' /usr/src/linux/.config

Not sure what you mean ... but no, they are not commands, you need to look under the respective sections in 'make menuconfig'.

ok so far all the stuff i should enable seems enables...
seems about right doesnt it

If you have an Atom N2600 (Cedar View), that uses PowerVR graphics and is not supported by xf86-video-intel nor the kernel's i915 driver.

To get an unaccelerated driver for it, enable CONFIG_DRM_GMA3600 in kernel menuconfig and install xf86-video-modesetting. There is also an accelerated proprietary driver from Intel for this hardware but I haven't seen it packaged for Gentoo yet.

ok ive installed the xf86-video-modesetting, but i cannot find the option to enable CONFIG_DRM_GMA3600 in menuconfig. im using the 3.7.10 kernel....could you give me the folder names in which youfind it in the menuconfig?i cant find it under "graphics support"
